In the figure, a 3.7 kg block slides along a track from one level to a higher level after passing through an intermediate valley. The track
is frictionless until the block reaches the higher level. There a frictional force stops the block in a distance d. The block's initial speed
is vo = 5.1 m/s, the height difference is h = 1.1 m, and Hk = 0.566. Find d.
